I had ordered a model, but this was already after 3 weeks on the broken strap and un usable. The support was so kind to me for free (!) Authorizes delivering a replacement, but which had the problem myself after a month. For the price good audio quality, but the longevity of something to be desired.
Updated: Due to this review me a third model was sent free of charge. The support is really impeccable. 4 stars
